Title: Method of driving can driver and drive control method
Inventor: OKAHARA AKIO
IPC: H04L12/40
Filed: 2002-11-20
Abstract: <P>PROBLEM TO BE SOLVED: To reduce the influence of a noise current in a CAN (control area network) communication system having a plurality of CAN buses.  <P>SOLUTION: In the CAN communication system 20, communication is done via two CAN drivers 23, 24 connected to two CAN buses 25, 26, respectively. A signal TX1 applied to the first CAN driver 23 is detected, and the CAN drivers 23, 24 are driven on the basis of the detected output of the signal so as to shift a timing when the signal TX1 applied to the first CAN driver 23 varies from a passive state to a dominant state, and from the dominant to the passive from a timing when a signal TX2 applied to the second CAN driver 24 varies from a passive sate to a dominant state and from the dominant to the passive. Consequently, a coincidence in the drive timing between the drivers 23 and 24 can be avoided and thus the influence of a noise current can be reduced.  <P>COPYRIGHT: (C)2004,JPO

Title: Friction stir welding device, welding tool, and friction stir welding method
Inventor: YOSHIKAWA TAKAO
IPC: B23K20/12
Filed: 2002-11-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a friction stir welding device by which the strength of the welded object subjected to welding and the welding strength of each welded member can be improved.  <P>SOLUTION: The device comprises a tool angular displacement driving means of allowing a tool holder to angular displacement driving around an angular displacement axis. The object 21 to be welded is sufficiently stirred by a welding tool 20, and, thereafter, the tool holder is separated from the object 21 in a state where the tool holder is subjected to angular displacement around an angular displacement axis. Thus, in the welded part of one member 21a, shape is made to differ between a transmission region 123 where force is transmitted and a non-transmission region 124 where force is not transmitted. In this way, the strength of the object 21 can be improved. Further, the welding tool 20 is swung in a state of being immersed in the object to be welded, so that a stirring region 21c can be increased, and the welding strength of the welded members can be improved.  <P>COPYRIGHT: (C)2004,JPO
